The Work-Energy Theorem: Friction
A car parked on a 32- degree steep hill loses its traction and starts to come down. It travels 160 meters on the hill until it reaches speed of 72 km/h. What is the kinetic coefficient of friction between the car and the surface?

If velocity of an object get doubled what happens to the Kinetic energy?
A small marble is launched from bottom of a rough 45º inclined surface with initial velocity of 20
m/s. The kinetic coefficient of friction between the marble and the surface is 0.5. When the marble
returns back to the bottom of the incline again, what is its velocity?
